It’s a hot day in Cape Town. This happens fairly regularly around this time of year, this being Cape Town and it being summer. Today was meant to get to 38 or 39ºC, depending on whom you chose to believe. But when we hung a calibrated and certified thermometer out of our lab window, we got a temperature of 41.1ºC.
This was in the shade, but it was obviously not in a Stevenson Screen – the official vented white box, 1.5m from the ground, which provides the standard conditions (in the shade, out of the wind, away from surfaces radiating heat etc) for measuring weather. But we don’t have a Stevenson Screen. We were just messing around hanging a thermometer out of a second floor window while we should have been
working eating our lunch.
And then we hung it in the sun. Now, to be in the sun, it did have to be a bit closer (within 30cm, perhaps) to a wall which had also been in the sun, but still – if you were where the thermometer was at 12:46pm this afternoon, this is what you would have been experiencing:
So no, despite my scientific leanings, this wasn’t scientific.
But our quick and dirty experiment does seem to indicate that Cape Town is bloody hot today.
Drink much, stay safe.
